我创建了一个包含URLField
和StringField
的简单表单。如下图所示:
from flask_wtf import Form
from wtforms.fields import StringField
from wtforms.fields.html5 import URLField
#from flask.ext.wtf.html5 import URLField
from wtforms.validators import DataRequired, url
class BookmarkForm(Form):
url = URLField('url')
description = StringField('description')
# override validate method of Form class for custom validation
def validate(self):
#app.logger.debug('Inside validate')
if not self.url.data.startswith("http://") or\
self.url.data.startswith("https://"):
self.url.data = "http://" + self.url.data
if not Form.validate(self):
return False
if not self.description:
self.description.data = self.url.data
return True
@app.route('/add', methods = ['GET', 'POST'])
def add():
#form = BookmarkForm(request.form)
form = BookmarkForm()
#if request.method == 'POST' and form.validate():
if form.validate_on_submit():
url = form.url.data
description = form.description.data
bm = models.Bookmark(url=url, description=description) # push to table
db.session.add(bm)
db.session.commit()
# store_bookmarks(url,description) # old method
flash("Stored '{}' '{}' ".format(url,description))
return redirect(url_for('index'))
return render_template('add.html', form=form)
但是,是什么导致验证覆盖不执行?
答案 0 :(得分:0)
我遇到了相同/相似的问题,在此代码中仅会评估第一个条件
if not self.url.data.startswith("http://") or\
self.url.data.startswith("https://"):
self.url.data = "http://" + self.url.data
您需要为OR逻辑添加():
if not (self.url.data.startswith("http://") or\
self.url.data.startswith("https://")):
self.url.data = "http://" + self.url.data
